Ok..... I can see that you haven't got a clue as to what I'm talking about. My opinion has nothing to do with anything here. It's a measurable effect that's easily proven.

Lets resolve this with pure logic then. There are two parts to this and the first is a question, the second is an experiment.

First Part.......
Lets say I give two people the same wave file to play back in their keyboards. One owns a KORG and the other owned a Tyros 3. Which do you think will sound better if they are both using the EXACT same wave file.

A: The KORG with it's new ENGINE.
B: The YAMAHA with it's 20 year old ENGINE.
C: They will both sound the same.

Second Part.....
I'll tell you the second part based on your answer above.

James.
